Failure to read lens information from exif data

[ast43989we23]

First of all, Timon, really awesome project.

I have an error and are wondering whether sb. else might have that error as well. When I found that RapidRAW does not recognize some of my lenses (only some, some are recognized) I investigated what the issue could be. The lenses are all part of the lensfun database and can also be found manually withing RapidRAW, i.e. that is not the issue.
I took a look at the exif data and realized that the lense information is not shown, I am wondering whether there is some bug in the way that RapidRAW reads exif data since in RawTherapee the lense information is displayed. You can also see that in the screenshots attached here - same raw file, one screenshot from RapidRAW (exif data section) and one from RawTherapee.

Would be interested whether I am doing sth. wrong or whether there is a bug in the way that RapidRAW reads exif data.

Cheers
